Using NASA's Chandra spacecraft, astronomers have discovered three new ultraviolet-bright radio-quiet quasars at high redshift and measured their basic X-ray properties. The newly found quasi-stellar object turns out to be the brightest in UV among the known high-redshift radio-quiet quasars. The finding is presented in a paper published November 2 on arXiv.org.
